Abstract

The invention provides a multi-channel point-to-point communication device and method based on a LoRaTM technology. The device comprises an MCU processor, a plurality of LoRaTM radio frequency modules, a power supply module and a sensor, wherein the MCU processor communicates with the LoRaTM radio frequency modules through an SPI interface and a GPIO interface to receive and send data; the LoRaTMradio frequency module transmits and receives data in an interrupted mode, and an NSS interface and an INT interface of the LoRaTM radio frequency module communicate with a GPIO interface of the MCU processor so as to carry out signal selection and interrupt signal processing. According to the invention, the MCU (microcontroller) is used for controlling the plurality of LoRaTM radio frequency modules through the SPI interface, so that the device can realize multi-channel parallel communication and full duplex communication of data, the bandwidth is greatly increased, and the communication requirement of time delay is reduced, thereby expanding the application scene of the LoRaTM technology and improving the user experience.

Description

technical field [0001] The present invention relates to the field of electronic information technology, in particular to a LoRa-based TM Technical multi-channel point-to-point communication device and method. Background technique [0002] Currently LoRa TM The technology has the advantages of low cost, long distance and low power consumption, but due to its narrow bandwidth, high delay, and half-duplex application characteristics, it greatly limits its inability to perform wireless communications in voice, image and real-time requirements. In addition, other wireless communication technologies have the inconvenience of short distance and high power consumption while ensuring a certain bandwidth. Contents of the invention [0003] In order to solve the deficiency of existing application characteristics, the present invention proposes a LoRa-based TM The technical multi-channel point-to-point communication device and method, while ensuring its advantages of low power cons...
